2021年11月10日,国家能源局综合司《关于推进2021年度电力源网荷储一体化和多能互补发展工作的通知》一经下发,全国各省市立刻跟进各种措施推进。一时间“源网荷储”成为每个企业,特别是大型集团、外企推进降碳目标的主题。然而,并不是所有企业都对“源网荷储”的概念有着清晰的认识。
“源网荷储”其实是“电源“、”电网“、”负荷“和”储能“的组合用语,它们之间通过源源互补、源网协调、网荷互动、网储互动和源荷互动等多种交互形式,以一种更经济、更高效和更安全的方式,提高电力系统功率动态平衡运行。它本质上是一种实现能源资源最大化利用的运行模式和技术。当新能源的比例越来越高时,因其波动性、间歇性,源网荷储的协调发展就显得尤为重要。
图扑软件利用大数据、云计算、边缘计算、人工智能等数字化技术,结合自主研发的HT 产品,构建的“智慧园区能源管理系统系统”安全故障预警应用平台,有效解决了困扰行业多年的储能安全问题,让“预防”优先于问题“解决”,云检测,免拆解,以最小的成本保障储能安全。

本发明的目的通过以下技术方案实现。
一种源荷储互补的能源电网反馈控制的人工智能物联网系统,基于多能互补电网模型和需求响应特征进行预测,然后根据设备实时的源设备的运行特征、出力数据、能源介质消耗指标,储能和负荷的实时实测数据对预测结果采用时间序列特征进行校正,并依据预测结果对模型进行修正,并用修正的数据对源设备、负荷和储能设备进行控制和监测,实时滚动修正,保证预测精度。
负荷需求响应中的需求响应特征综合考虑了电力价格,家庭收入,家庭规模,户主年龄和家庭环保意识因素对家庭电力需求的影响,从需求价格弹性,需求收入弹性,需求规模弹性,需求年龄弹性和需求意识弹性的角度刻画了用户异质性。
基于智能量测技术、大数据分析实现用户用能数据的深度挖掘,支撑用户用能策略优化、设备运维托管、行业政策制定业务。
感知层通过部署智能终端设备实现数据的采集、汇聚功能,包括智能电表、射频卡采集、边缘网关设备,数据分析层对基础数据进行整合、集成分析,为高级应用提供数据支撑,涵盖设备、用户、行业三个维度,业务应用层则面向用户开展各项高级应用,所述用户既可是能源消费者,也可是能源供应商。
利用超短期预测数据调度指挥负荷的变化,而负荷出力的变化对预测数据又有管控的作用,当预测数据和实际数据误差较大时,需要对历史数据重新进行聚类分析、机器学习得出误差分布状态,得出最新的下一刻预测状态。
构建大规模的能源管理对话语料库[<Post,Response>),Post表示问题,Response表示对应回复,从语料库中可以学习到能够表达Post与Response之间语义关系的相关性模型;其次,通过检索的方法从语料库中检索出与Query相关的候选语料子集;最后通过相关性模型计算Query与子集中Response的相关性,取相关性得分最高的Response作为回复。
相比于现有技术,本发明的优点在于:1)将系统性思维和数字化技术与能源生产、传输、存储、消费以及能源市场深度融合的新型生态化能源系统,目标以可再生能源优先,以电力为基础,通过多能协同、供需协同等找到“能源不可能三角”的平衡点。以新能源为主体的新型电力系统是能源互联网双碳目标下现阶段发展的核心形态。依托新型电力系统建设,整合各类型能源资源,新型电力系统将逐渐发展为更加柔性、更加开放、高度智能的能源互联网系统,并形成新的智慧能源的商业模式和生态。
2)从系统边界关系角度来看,源荷储云网平台需要采集电站侧各系统数据并汇聚到数据汇聚服务器,通过数据汇聚服务器对站内系统进行数据采集并传输。从应用分布角度来看,储能云网平台将实现规划设计、运行监测、智能运维、运营分析、设备资产、调度控制、交易结算、能效管理等各类业务应用功能。
